Table 2 The method of systematic text condensation as described in four steps

1. Read all the interviews to gain an overall impression. This overall impression is summarized in four to eight preliminary themes.

2. Identify meaning units in the data, separate relevant text from irrelevant, and sort the meaning units into code groups.

3. Sort the content of each code group into two or three subgroups. The meaning units in each subgroup are abstracted into condensates in the first person.

4. Each condensate in each code group is summarized as an analytical text and validated by re-reading the original transcripts.
